Added support for `-stdlib=`.

I made the assumption that `-stdlib=libstdc++` implies the user wants libsupc++ as their ABI library, though someone may want libstdc++ + libc++abi, or other combinations. If that's the case, we can add `-abilib=`, and likewise `-unwinder=`... but let's save that for another patch, on another day.
